Four out of the five Republican state lawmakers targeted for defeat by conservative radio talk show host Dan Proft survived their primary election challenges on Tuesday, with House GOP leader Jim Durkin saying he doesn’t “think the voters are necessarily supportive of extremes.”

Proft’s chosen candidates, though, did win primaries in several districts where sitting lawmakers didn’t run for re-election, and his political action committee scored a victory by defeating state Rep. David Reis of Downstate Willow Hill. Reis was one of several Republican lawmakers who sided with Democrats to initially vote in favor of last summer’s income tax hike.

And Proft-backed state Rep. Jeanne Ives came close to scoring a historic victory, nearly toppling Republican Gov. Bruce Rauner. Proft, who ran for governor in 2010, declared Wednesday on Twitter that “the revolt against the ruling class fell a little short but the reckoning will come.”

A Proft bid to defeat Durkin also came up short. The Western Springs Republican overcame a rare primary challenge, which stemmed from last year’s showdown over the tax and budget package. Durkin voted against the measures, but Proft questioned his leadership after the party didn’t remain united against the tax hike in a chamber controlled by powerful House Speaker Michael Madigan, who is also head of the Democratic Party of Illinois.

Proft didn’t return messages seeking comment.

His Liberty Principles PAC independently spent more than $1.2 million to back Burr Ridge Village President Mickey Straub, who lost with 32 percent of the vote to Durkin’s 68 percent. Durkin raised $1.7 million to defend his seat in the western suburban district, and he was helped along by more than $500,000 from the state Republican Party, which Rauner heavily subsidizes.

“I think voters, they want to see people who have proven records,” Durkin said shortly before declaring victory on election night. “I don’t think the voters are necessarily supportive of extremes. I work hard, my campaign works hard. We did it old school. I work, and I talk to my constituents. That’s what I did in the course of this campaign.”

Proft’s political action committee spent another $335,000 in an unsuccessful attempt to beat Rep. Norrine Hammond of Macomb and $257,000 in a failed bid to beat Rep. Terri Bryant of Murphysboro. Both voted for the tax hike and in favor of overriding Rauner’s subsequent veto. The group spent an additional $268,000 to back the candidate who lost to Rep. Charles Meier, who voted for the tax hike but then switched positions and voted against the override of Rauner’s veto.

Another $465,000 went for Katie Miller, a nurse who was seeking to replace outgoing Rep. David Harris of Arlington Heights. Miller lost to Eddie Corrigan, outreach coordinator for U.S. Rep. Peter Roskam, who was backed by the House Republican Organization to the tune of $394,000.

Liberty Principles PAC received $5.5 million in funding from conservative donor Richard Uihlein, a Lake Forest packaging company magnate.

Among Proft’s successes on Tuesday: Former state Rep. Dwight Kay won his primary after receiving more than $173,000 from Liberty Principles. He’s seeking to reclaim the seat he lost in 2016 to Rep. Katie Stuart, a Democrat from Edwardsville. The committee also helped DuPage County Board member Tonia Khouri to victory, and Schaumburg Township Library District Trustee Jillian Rose Bernas was assisted by at least $186,000.

Bernas faced Charlotte Kegarise, who was backed by Durkin’s House Republican Organization. Bernas will now face Democratic state Rep. Michelle Mussman in the November election. Republicans sought to play down the loss on Wednesday, saying it’ll be a difficult seat for the GOP to win.

For his part, Durkin said it’s time to for Republicans to focus on governing instead of fighting off attacks from inside their own party.

“I’ve got to be able to pivot and start working on issues about balancing the budget, property tax relief and deficit reduction. And I’m prepared to do that. It’s good to have this out the way,” Durkin said.
